The Hawk was on the same settings the whole time, the top switch (a volume toggle?) was to the right, middle switch (gate?) was open, to the right, and the bottom switch (gain/eq?) was in the middle. The looper I used was a Digitech Jamman Express and to get different pitches of feedback I switched from a capo on the 4th fret to no capo. The oscillation at the end is coming from a Death By Audio Ghost Delay that's on for about the last minute of the recording. A lot of the other variations in the sound are from muting and unmuting strings, moving the guitar closer to the amp, and switching between feedback over a loop of layers of noise and just feedback. I used the built in mic on this Tascam 8-track and an SM58 close mic'd mixed in stereo.

TAFM with an additional octave. signal chain is jazzmaster > (tuner) > mini > HoF > TAFM > silverface fender twin.there is some clean blended in so the octave isn't quite as pronounced as it can be. i turn it off here and there and use the other stuff as well - just messing around really but there are some excellent textures in there.
